Description

Sorbitan, Di-9-Octadecenoate, (Z,Z)- is a non-ionic surfactant and emulsifier derived from sorbitol and oleic acid. This compound is valued for its ability to stabilize oil-in-water emulsions and function as a versatile dispersing agent in complex formulations. It is primarily needed by manufacturers in the cosmetics, personal care, food processing, and industrial lubricant sectors for creating stable, high-performance products.

Application

• Cosmetic & Personal Care Formulations: Acts as a key emulsifier and solubilizer in creams, lotions, and makeup products.
• Food Additive (Emulsifier): Used as a food-grade emulsifier (E-number series) in baked goods, confectionery, and edible spreads.
• Pharmaceutical Excipient: Serves as an emulsifying agent in topical ointments, creams, and certain oral suspensions.
• Industrial Lubricants & Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in water-based lubricant systems.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Textile & Leather Processing: Employed as a softening agent, lubricant, and dye dispersant.
• Paints & Coatings: Acts as a pigment wetting and dispersing agent to improve color consistency and stability.
• Plastic & Polymer Additive: Used as an internal or external lubricant and anti-static agent in polymer processing.
